Bound value in a conditional binding must be of Optional type [IOS - SWIFT] -

-

i trying make to-do list app in xcode using swift, , encounter error writing 1 of function methods on "if let path = indexpath {" line says "bound value in conditional binding must of optional type".

func tableview(tableview: uitableview, cellforrowatindexpath indexpath: nsindexpath) -> uitableviewcell {     let cell = tableview.dequeuereusablecellwithidentifier("cell", forindexpath: indexpath) as! uitableviewcell     if let path = indexpath {                     let currentstring  = datasource[path.section][path.row]         cell.textlabel?.text = currentstring                 }             return cell } 

func tableview(tableview: uitableview, cellforrowatindexpath indexpath: nsindexpath) -> uitableviewcell {         let cell = tableview.dequeuereusablecellwithidentifier("cell", forindexpath: indexpath) as! uitableviewcell         cell.textlabel?.text = datasource[indexpath.section][indexpath.row]         return cell }

use code because think previous idea not good.

you don't need conditional binding here suggested leo.

javascript - Create websocket without connecting -

is there way create websocket without connecting right away? far think var ws = new websocket("ws://ws.my.url.com"); creates , connects right away. i'd create socket, define callbacks, , connect once user clicks connect button. thanks no. creating websocket means you've created connection server (or started process of connecting). there no such thing creating websocket isn't connecting yet. you create object store configuration parameters , tell object connect when wanted to, though i'm not sure why that's better creating actual websocket when connect made. or create function setup work , call function later when user clicks connect button.
